[talk-au] miniround abouts and sunshine council
Does anyone know if the sunshine council has a minroundabout option in its regs? Specifically the roundabout near bigtop plaza if you go straight in from the bruce highway It's slightly elevated by 5 to 10cm and no bigger than 2m in diameter and the T-intersection it would have replaced doesn't look to be deformed at all, would post a pic but the browser on this phone doesn't let me add attachments. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
Re: [talk-au] Someone needs some help.
In JOSM you can select a large number of objects based on a rule. Such as select all nodes with highway=gate. Then when you change a property it will change it on all selected nodes. This is what I did to add maxspeed=50 to every residential street in Newcastle. It won't help for the street names though. - Original Message - From: John Smith Date: Monday, June 22, 2009 10:36 am Subject: Re: [talk-au] Someone needs some help.

I got the following replies from Xoff... Didn't help me, but might help you...
If you want to change the excluded area there you just need to change the
following lines:
POLYGONS[0]=${DIR}/polygon1.arc
echo $'52.23 -0.3
52.34 -1.2
52.65 -0.3
' > "${POLYGONS[0]}"
Replace the coordinates between $' and ' > with the corners of the area you
want to exclude. So with the coordinates you mentioned it should look like this:
POLYGONS[0]=${DIR}/polygon1.arc
echo $'-33.0 150.0
-33.0 151.0
-34.0 151.0
-34.0 150.0
' > "${POLYGONS[0]}"
I just noticed that there was a bug in the script. I accidentally had copied
the code fore the second area two times into the script. I have updated this
now.
You may be able to find more information about the polygon files in the
gpsbabel documentation. Because what I do in the script is basically creating a
file for each polygon and then calling gpsbabel. Since I had a number of areas
to exclude I added the filenames to a bash array and called gpsbabel for each
filename in the list.
I had a look at the gpsbabel documentation
(http://www.gpsbabel.org/htmldoc-1.3.6/filter_polygon.html). Apparently, the
polygons must be closed. Repeating the first coordinate at the end of the list
should work.
I better fix this in the script on the wiki-page and add a comment. When I
uploaded the script I changed the polygons and forgot about this detail. I'm
sorry about that!

I wasn't aware of this. I also just went to check but there is no mention on either the upload page or the wiki page for help the upload page links to about what the public/private option means or the ramifications. I didn't dig any further, but this seems like a pretty bad way to handle possibly sensitive data from users. I was under the assumption that it meant only you would be able to see the traces in any editors that downloaded/shows the GPS trace. I originally had uploaded GPX files to then use them in potlatch but have since removed them for privacy reasons until I can sort out a batch processor for them. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

In this case the only real information OSM has on these people are their traces, so we would need some sort of protection in place if they are worried about this sort of thing. One solution might be to always drop the last and first N minutes, kilometres, turns, etc. from every journey, where N is a random number chosen uniformly from a fairly wide range (between 5 and 10 minutes). This would ensure that most of the travelling information is kept, but no information about start points and destinations are. These end points would be less likely to be useful for road-speed modelling anyway. Also, does everyone here realise that private traces still show up for everyone in JOSM/Potlatch/etc. (without any timestamp or user information)? It just means that the files are not visible in your traces area on the website. Ie. the gps points themselves are still publically accessible through the API, you just can't tell who made them or at what time they were made. - David -- View this message in context: http://www.nabble.com/Hi-all-...-tp24072661p24134109.html Sent from the OpenStreetMap - Australian Talk mailing list archive at Nabble.com. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

You should check out Telstra's profit sheets some time on silent numbers, there is a lot of people paying a lot of money to keep themselves out of the phone book.

Even when it does work, it's still more hassle than it's worth imho. Also gpsbabel is proving to be too much of a hassle to anonymise files as well, so I've decided to bite the bullet and just code my own java or shell script to parse gpx files, strip out everything except time, lat, lon, HDOP/VDOP and elevation. Then reset the timestamps to epoch, rather than randomising them which seems to be a bit crude and doesn't gain much. Also I've been pondering about the time difference between GPS points and ranomising it a little to be useful if police ever started to use the information in GPX files to charge you with a speeding offense and all the hassle of taking it to court to beat it and what not. For those of you that claim you never speed, what about those pesky school zones without flashing lights that you can't tell the times they are in force until you are virtually on top of them and have to sit and think about if the time actually applies at this point in time and slamming on your breaks if it does to prevent yourself from going in excess of the speed limit. Even if you do reset the timestamps it may be possible for the police to find out when you went through the school zone even if the clock on your dash board says the school zone speed doesn't apply because it's inaccurately set. Although if the GPX files are uploaded through a shared account this would reduce the risk of this sort of problem. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

Also it has no batch function. To do what you want to do, you need to do this: Open GPX file, click the "edit GPX" button that appears on the left side tool bar, click ok, remove or delete the old gpx file from the layers box, then select "convert to gpx layer with anonymised time", then go tools and upload traces. The time stamps should get converted to random or unix epoch start time, but they do exist and have worked fine for uploading. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au

Sure, it's a cat and mouse game which I've been going over in my head to try and work out a solution to. One possible solution is to randomly upload them via the account I created which I use to accept auto uploaded GPX files from hundreds of other people. The downside with this solution is that most people submitting traces this way aren't in Australia so that probably won't help much for the GPX files I've created in Australia. So to solve this problem I just need to make similar apps for other handsets that people would use in Australia. It's all about how much time and effort you can and are willing to commit to such problems. ___ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
